Just had a very quick look at Dr Lowe's pages and read that Propranolol is a no-no,as it's a thyroxine blocker. I was put onto it when I was hyper to get rid of tremor. I'd been taking it for some years after RAI sent me hypo,not knowing. When "they" realised, they asked me to tryto come off it; I did butthe tremor returned with a vengeance and my GP rapidly put me back on it. Does anyone know of an alternative I could try? I do still shake markedly but I've learned to cope with it. It would be nice to get shot of the shakes altogether and get off Propranolol.
